The Black Cat Project Espresso Tamper arises from a collaboration between Intelligentsia baristas, the artisans at Reg Barber. It has been painstakingly designed to fit perfectly in the hand, regardless of the size of the barista using it. Additionally, the base of this tamper is convex. The overall effect is one of high design, and this tool will become a treasured object for both espresso aficionados and professional baristas alike. Tamper base size is 58mm.
